I'll use this thread to post interesting items I find in the 12-volume revenue accumulation I purchased. The images are high resolution, so you may want to click on them to open in a separate window.
First, there are the 3 pages below. The first two are the items that I had pulled out Thursday night to buy at retail before I thought about buying the whole collection (yes, I showed these to the seller before we started negotiations).
The third page is the items I found yesterday after buying the collection.
PAGE 1:
Row 1, stamp 3. Silk paper.
Row 2, stamp 2. Great embossed "Castor oil" cancel in Old English font.
Row 4, stamp 7. Clapp & Co's Magic Ball. Eric has one in inventory at $200.
Row 5, stamp 2. VERY rare "War Tax" cancel. Richard prices this at $300.
Row 5, stamp 3. Not only a neat manuscript block cancel, but the stamp has a doubled top frameline.

PAGE 2:
Row 1, stamp 2. Brown ink cancels are exceptionally rare, more so than green ink.
Row 2, stamp 5. The Naylor & Co. cancel normally found is the diminuitive oval cancel rather than this one.
Row 3, stamp 2. Unusual unattributed "K&B" monogram. I have this cancel also on an R22b.
Row 3, stamp 3. Great embossed shield.
Row 3, stamp 4. A (presumably) Simon de Visser cancel I've not seen before. The most common are the circular and the SdeV large roman letters.

PAGE 3:
Row 1, stamp 2. "Dr. Hopkins Magic Powder" with "KEEP CLOSE CORKED" in the center. Very rare. $250.
Row 2, stamp 1. Lesser state of T13a double transfer (bold at bottom, but nothing at top).
Row 2, stamp 2. Greater state of T13a on silk paper (unlisted in Scott).
Row 2, stamp 3. Unlisted all-over double transfer.
Row 2, stamps 4 and 5. Two different states of T15 double transfer.
Row 2, stamp 6. Double transfer, doubling down right side.
Row 3, stamp 5. Unidentified oval silhouette.
Row 5, stamps 1-4. All silk papers (R53d with double transfer).
Row 5, stamp 5. Hart L. Pierce counterfeit.
